And thus, it came to be that a video slot was designed to work around the music, and not the other way around, which is the usual scenario.
Granted these are all fun facts, but they quickly lose their charm if the actual slot is a disappointment.
Fortunately, that is not the case: Hall of the Mountain King is very much a success. Graphically speaking it is a masterpiece, the music is divine, and the bonus round is exhilarating, even though it takes a bit of an effort to figure it out.
Hall of the Mountain King is not only one of the most ambitious projects undertaken by Quickspin; it has also ended up being one of the most outstanding ones they have ever released.

Hall of the Mountain King gameplay and features
Hall of the Mountain King is set in a beautiful world full of trolls, elves, Orcs and mysterious caves. And every time we think that a slot by Quickspin has reached the ultimate level as far as beautifully designed graphics go, the design team at this Swedish game developer proves us wrong again. This slot looks phenomenal.
The game has 5 reels with 3 rows of symbols and 20 fixed paylines.
The betting ranges between $€ 0.20 and $€ 100 per spin.
Hall of the Mountain Kins is a high variance slot: the maximum payout is 7,000 x the total bet. That is certainly worth getting up for!
As far as the slot’s payout rate is concerned, Quickspin scores big time as well with 96.29%.
Symbols and payouts
The wilds replace all symbols, except for the scatters and are, together with the Mountain King himself, the highest value symbols in the game. Both of them will reward you with 40 x the total bet when you hit 5-of-a-kind.
The medium value symbols (various trolls and elves) are worth between 7.50 x and 20 x the total bet with five identical symbols.
The card symbols are the low-value symbols, and they will get you anywhere from 2.5 x to 6.25 x the total bet if you manage to spin 5 of the same on an active payline.

The more wilds drop on the reels, the higher the multiplier goes. The maximum multiplier is 5 x. Clearly, this mechanism was ‘borrowed’ from the Netent slot Lost Island.
Free spin bonus
The free spin bonus in this slot is won by spinning three scatters on the middle reels.
It consists of 3 levels.
Although it would get to be a bit much to explain the bonus round in detail, it kind of goes like this:
1st round: high-value symbols replace the low-value symbols by creating winning combinations.
2nd round: here the winning combinations get you extra wild symbols. You can collect up to a maximum of 6 wilds.
3rd round: All collected wilds are now brought into the game at random times and sometimes will earn you extra multipliers.
The Mountain King himself can also give you a real boost by doling out extra multipliers. Besides that, he also crushes the rocks that contain the upgrades when you produce winning combinations.
The more (and the faster) you can make winning combinations, the more money you can make in this very cool bonus feature.

The minimum deposit for the welcome offer is $50, which is a bit higher than most other online casinos I gotta admit. However, if you don’t mind the steep deposit, you can get a pretty decent starting bonus to try out what this casino has to offer.

While this bonus seems like it has everything going for it, there are some things to consider before activating it. Primarily, the 35x wagering requirement is not too bad, it’s the average for many bonuses. However, you’ll need to play this through within 48 hours and you have a maximum bet of €3. Additionally, the maximum win you can withdraw is 10x the deposit made.
